Two-dimensional Electrical Resistivity Tomography was done on failed portions of Southsouth Benin – Akure Expressway, in Ovia Northeast LGA, to establish the subsurface geological formations responsible for the pavement failure and provide geotechnical support for its maintenance. The survey was done on five worrisome portions of the highway, namely; Igbekhwoe, Odighi, Odiguetue, Omigie and Ugboke communities respectively, using Wenner array electrode configuration to obtain one profiles of 100 m length on both sides of the road at each location.
